Abstract：The content of lead and arsenic in toothpaste was determined by ICP-MS，The recovery rate and repeatability can completely meet the experimental requirements. Therefore，ICP-MS can be used to determine lead and arsenic in toothpaste，which not only simplifies the experimental process，improves the work efficiency，but also reduces the experimental cost.

Key words：toothpaste；ICP-MS；lead and arsenic content
